Fatented Mar. 17, 1931 PATENT; OFFICE ALFRED R. PAGE, OF KEEGO HARBOR, MICHIGAN VENTILATING DEVICE Application filed June 26,

This invention relates to certain novel improvements in ventilating devices and has for its principal object the provision of an improved construction of this character which will be highly efficient in use and economical in manufacture.

The salient object of my invention is to provide a device which may be used for ventilating a' room which will be arranged so as to prevent a draft and this is accomplished by providing an effectively counterbalanced member which may be arranged to remain in open position until an air current of apredetermined force passes through the device.

Another object of the invention is to provide a device of the above described character which will be arranged so that it will shut ofi in the event a strong air current passes therethrough or in the event of rain being blown toward the device which might pass into the room being ventilated.

Another object of the invention is to provide a device of the above described character which may be associated with a window construction.

A still further object of the invention is to provide a device of the above described char acter which will be of adjustable length in order that it may be associated with different size window structures or openings.

A still further object of the invention is to provide a device of the above described character which may be locked in open position and which may also be locked in closed position.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be herein- I .15 a recess 21 is defined which has 'arod 22 after described and claimed. The invention will be best understood by reference to the accompanying drawing, showing the preferred form of construction and in which:

Fig. 3 is a fragmental view of the device as illustrated in Fig. 2 and drawn to an enlarged scale and looking in the opposite direction from Fig. 2;

Fig. 4 is a sectional view taken substantially on the line 4-4 on Fig. 3;

Fig. 5 is a sectional view taken substantially on the line 5-5 on Fig. 3; and

Fig. 6 is a fragmental view depicting the adjustable end portions of my improved device.

In the accompanying drawing wherein I have illustrated a preferred form of construction for my invention, 10 generically lndica'tes a window construction in which a sash 11 is mounted for vertical movement The sash 11 is intended to be spaced from the sill 12 in an amount suflicient to permit my improved device to be mounted between the rail 13 of the sash 11 and the sill 12.

My improved device includes a frame generically indicated by 14 which includesan upper rail 15 and a lower rail 16 and end rails 17 and 18. The rails 15,16, 17, and 18 in the present instance are shown as being formed from wood but it is to be understood that these rails might be formed from metal or other material without departing from the purview of my invention.

It is manifest that the rails hereinbefore set forth define an area which is preferably closed by a wire mesh screen 19 which is extended over the area defined by the rails and which is fixed to the rails. A strip 20 is disposed over the ends of the wire mesh screen, so as to conceal these ends and thus enhance the appearance of the device.

In the outwardly disposed face of-the rail secured to the plate 28. The U-shaped strip 24 is intended to be disposed in the recess 21 so that the rod 22 will be disposed in thebight 05 of my device in such a position I provide a portion of said U-shaped strip and in this manner the plate 23 is hingedly mounted in position. The plate 23 may be formed from metal, glass or other material and it is manifest that when the plate 23 is in abutment with the frame 14 air passage through the frame 14 will be prevented.

Extending between the rails 15 and 16 substantially midway between the rails 17 and 18 is a strip 25 on which a portion of the operating portions of my device are intended to be mounted. These operating portions include a hinge generically indicated by 26 which has one leaf 27 thereof secured to the rail 25. A plate 28 is secured to the leaf 29 of the spring 26 and is mounted for swinging movement. As best illustrated in Fig. 4 the plate 28 preferably embodies right angularly extending edges connected by a rounded edge. Connected to the plate 28 outwardly from the portion thereof connected to the leaf 29 is an arm 30. This arm 30 is preferably pivotally connected to the plate 28 as indicated at 31. v

In the strip 25 a slot 32 is formed. A plate 33 is extended through the slot 32 and is connected to the plate 23 adjacent the upper edge thereof. The arm 30 is pivotally connected to the plate 33 as indicated at 34. Therefore, when the plate 28 moves outwardly about the hinge 26, movement thereof is transmitted through the arm 30 to the plate 33 which causes this plate to pass through the slot 32 and thus move the plate 33 outwardly and this outward movement of the plate 33 is about the rod 22.

Mounted on the strip 25 below the hinge 29 is a substantially U-shaped supporting rod 35 over the bight portion of which a sleeve 36 is moved. A set screw 37 is provided in the sleeve 36 which permits the sleeve to be attached on the member 35 in different positions. Extended between the sleeve 36 and the plate 28 is a spring 38. By positioning the sleeve 36 at different points on the member 35 the tension of the spring 38 may be varied. By varying the tension of the spring 38 in this manner the position of the plate 23 when moved outwardly relative to the frame 14 may be determined as this spring tension may be adjusted to effectively counterbalance the weight of the plate 23 and the air pressure acting thereagainst.

On the upper side of the rail 15 I mount a strip 39 which includes an angularly disposed portion 40 that extends outwardly from the front side of the frame 14 at an angle thereto and this portion 40 serves as a rain deflecting strip.

It has been pointed out that my improved device may be mounted between the lower rail 13 of a sash of a window construction and the sill 12 of such a window construction. In order to permit effective clamping yieldable strip 41 exteriorly of the strip 39. This strip 41 may be formed from rubber or similar material and it is therefore, manifest that the device will be very effectively clamped in positon by the rail 13. This strip 13 will also prevent insects from passing between the juncture between the rail 13 and therail 15 ofmy' improved device.

l/Vhen the plate '23 is formed from' metal or other material it is preferably reenforced by a reenforcing strip 42 which extends thereacross adjacent the lower edge thereof. I11 addition to the reenforcing strip 42 a similar reenforcing strip 43 extends between the strip 42 and a point adjacent the upper end of the plate 23 and in this manner the plate 23 is effectively reenforced.

As best shown in Fig. 6, provided in the end portions 17 and 18 are slots 47 and similar slots are provided in extension strips 44 and 45 which are slidably mounted on the end portions 17 and 18 by means of bolts 46 which project through the slots 47, and these bolts carry washers 48 and wing nuts 49. It is manifest, therefore, that the strips 44 and 45 may be extended to fit the size of the window casing.

In the plate 33 I provide openings 50 and in the edge of the plate 33 I provide a notch 51. A latch 52 is p-ivotally mounted on the strip 25 as indicated at 53. The latch 52 has a lug 54 thereon which extends therefrom toward the plate 33 and which is aligned with the openings 50. When the latch 52 is moved toward the plate 33 the lug 54 enters one of the openings 50 andin this manner the plate 33 may be locked against movement and, therefore, the plate 23 may beheld in de-.

termined positions relative to the frame 14. A spring clip 55 acts on the end portion 56 of the latch 52 to retain the latch in said position. The latch 52 includes a handle portion 57. By gripping the handle portion 57 the latch 52 may be turned into a substantially horizontal position wherein it will bear on the curved edge 58 of the plate 33 and when the plate 33 is in the position depicited in Fig. 4 wherein the plate 23 is in abutment with the frame 14 the end portion 56 of the latch 52 will pass into the notch 51 which is disposed so as to permit this and, therefore, the plate 33 is held against movement and consequently the plate 23.

. On the front face of the lower rail 16 and on the front face of the side rails 17 and 18 I provide a gasket 58 which is preferably made from a resilient material such as rubher. This gasket or washer serves to absorb the shock when the plate 23 is rapidly moved into closing position relative to the-frame 14.-

If desired such a gasket may also be extended across the top rail. An arrangement such as the foregoing 1s particularly advantageous for use in connection with the plate 23 when the same is made from glass or similar breakable material.

In use the device is mounted in a suitable opening into a room and in a window structure in the manner set forth. If desired the plate 23 may be moved outwardly from the frame 14 in a predetermined amount and locked in this position by inserting the lock 54 on the latch 52 intoone of the openings 50. Therefore, air may freely pass through the wire mesh screen 19 into the room. However, if it is desired to arrange the device for automatic operation so as to prevent an excessive draft the sleeve 36 is disposed on the bight portion of the supporting member 35 in a predetermined position. In this manner the weight of the member 23 may be counterbalanced so as to hold the member 23 in a predetermined position with respect to the frame 14:. In the event of an excessive draft acting on the plate 23 as it passes through the frame 14 it is manifest that this excessive air pressure will overcome the force of the spring and will move the plate 23 into closing position relative to the frame 14. If desired the end portion 56 of the latch 52 may be moved from engagement with the spring clip 55 and may be disposed in engagement with the edge 58. Therefore, if the parts are in this position and the air pressure moves the plate 23 into abutment with the frame 14 the end portion 56 will enter the notch 51 which will lock the plate 23 against further movement. This arrangement is preferably employed to prevent rain entering into the room and it is manifest that this device will function in this manner to effectively prevent excessive draft.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification, without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the ap pended claims.
